Everton new boy McCarthy: I once trialled with Liverpool!
However, the move did not work out for the Republic of Ireland international who now calls Goodison Park his home after a nervy deadline day move from Wigan Athletic for £13million.
"I went down to Liverpool for a week's trial. It wasn't to be, I was too young at the time. I didn't want to move away from home," he said.
"To be honest, the way things have worked out, I am happy.
"It was very hectic. At times it goes through your head that it might not happen.
"As time went on, it got to 10.30pm at night and I was thinking to myself, 'Is it going to happen or not?'
"I'm just delighted to be at such a great club. It is a great place to be. Since I heard they were interested I wanted to come here."
